DHD154a

DHD154a is a double coiled-coil structure.

Usage

To increase the modularity of our system we decided to test coiled coil proteins. These coiled coils mimic the interactions of DNA helix-helix interactions. The coiled-coil protein interaction allows the loading of more than one protein and larger proteins. We are using these helical structures to load RNA binding proteins into exosomes or virus-like-particles.

Biology

We generated helical bundle heterodimers in which each monomer is a helix–turn–helix starting from four-helix backbones produced using a generalization of the Crick coiled-coil parameterization.^[1]
